The pair have been battling for a spot on Chelsea’s right wing since Pedro arrived in a £21m deal from Barcelona, according to BBC Sport. In their absence, Ramires could start against the Gunners.

But Arsenal are six points better off than Chelsea after five games of the Premier League season, and beat them 1-0 in August’s Community Shield for Wenger’s first ever win over Mourinho.
